Description
Temperature and humidity sensor, similar to the popular DHT11 or DHT 22, with digital I2C interface in the through-hole case. The system can be controlled using a microcontroller or any commissioning set , for example,Arduino. Before using, you need to see thedocumentation.
Parameters:
- Supply voltage: 3.3 V to 5.5 V
- Average current consumption: 0,35 mA
- Temperature
- Measurement range: -40 °C to +80 °C
- Resolution: 16 bits (0.1 °C)
- Accuracy: 0.5 °C
- Response time: 2 s
- Humidity:
- Measuring range: 0% to 99.9 % RH
- Resolution: 16 bits (0.1% RH*)
- Accuracy ±3 RH* (at 25 °C)
- Measuring range: 2 sec
Details inthe documentation
*RH- relative humidity is expressed in percents. It is the ratio of actual moisture in the air to the maximum number that the air can keep at a given temperature.

The product is compatible with Arduino Online, available is library for Arduinowith a description of the connections which simplifies the maintenance of the sensor. |
Example of connection with microcontroller
The diagram shows the method of connection of the system with any microcontroller using the single-wire interface.
VDD - supply voltage, SDA and SCL - data and a clock line with pulling-up resistors of 10 k Ohm, GND - the ground of the system.
